300LB THD Flanges ASTM A182 F316 Flanges

Blind flanges are used to seal the end of piping systems or pressure vessel openings.

ASME B16.5 SW flange is belong to American Standard for forged flanges,this kind of flange are been used all over the word.Forged flanges are high pressure flanges,the commonly used classes are CL 300,CL 600 for forged flanges.Stainless steel flanges always more expensive than other flanges because of the stainless steel has better functions.

Materials of WN Flanges

The specification of ASTM A182 Forged Pipe Fittings includes forged fittings, stainless steel, rolled alloy, forged alloy, pipe flanges as well as high-temperature service. Later then forgings and hot working, it would be cooled down to a certain temperature before heat treatment.

These pipe flanges are attached by inserting the pipe into the socket end and applying fillet weld around the top. This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.

What is a blind flang,what about its specification and advantage.

An assembly with limited space may be an instance in which a socket weld is selected, provided the pressure class is comparatively low and the fluid is not corrosive or for extremely high temperature service.

All flanges are round disks with holes for bolts around the rim, but the commonalities end there. a projecting flat rim used for strengthening or attachment.

The common material grade of stainless steel ASTM A182 contains F304/304L/304H, 316/316L, 321, 310S, 317,347,904L， 1.4404, 1.4437.

300LB SO flanges is a commonly used pressure of flanges,all flanges could be 150LB,300LB,600LB,900LB,1500LB,2500LB.Stainless steel forged flanges are always used in chemical environment because of the great anti-corrosive function.The most popular stainless steel grades are A182 F304/304L and A182 F316/316L.

900LB slip on flange can slip on the pipes and welded with the pipes.Stainless steel flanges are popular because of the an-ti corrosive function.Stainless steel flange can used over 50 years.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.

Flange connection is to fix two pipes, pipe fittings or equipment on a flange first, and then Flange pads are added between the flange plates and fastened together with bolts to complete the connection

Detail infoemation of Weld Neck(WN) Flange

Steel Pipe Elbow is the most common pipe fitting that changes the direction of the pipeline. It plays a important role in the piping system.

It is generally used in non-corrosive, non-critical, moderate pressure services. Slip on flanges of Class 150 and Class 300 are most commonly seen in utility engineering. Similar to welding neck flange, the slip on flange conforming to ASME B16.5 may generally be furnished with three facing types: raised face (RF), flat face/ full face (FF), or ring type joint (RTJ).

TOE means threaded at one end when translated. Thus, we can say that a nipple TOE is a nipple that has one threaded end.
In this case, we have the acronym TBE for “threaded both ends” which means threaded at both ends. In other words, this is the most typical type of nipple as described above for connecting two parts or fittings with female threading.

P280GH weld neck flange refers to a flange connection method that uses P280GH material as the base material and forms one or more layers of P280GH material welding layers on the flange surface through the butt welding process to improve the flange’s high temperature resistance, high pressure resistance and corrosion resistance.

The descipton ,specification ,and advantages of a weld neck flange.

Large diameter flat welding flange has less high-pressure suitability compared to its weld neck counterpart. The basic ring style is suitable for the occasion of low pressure. The butt weld category of the flange is known as a weld neck flange. It suits the occasion of high temperature and pressure as defined in the ASME B16.47 code.

Welding neck flange benefits

This allows for a smooth bore and better flow of the fluid or gas inside of the pipe. The connection with the pipe is done with 1 fillet weld, at the outside of the flange. But before welding, a space must be created between flange or fitting and pipe.

A105 WN flange is a carbon steel flange according to ASME B16.5.STD is represents the thickness of the flange.Flanges have many pressures:CL150, CL300, CL600, CL900, CL1500, CL2500.Flanges have five face types:RF RTJ FF MF TG.

A182 F316‌ lap joint flange uses flanges, steel rings, etc. to put the flange on the pipe end, so that the flange can move on the pipe end. The steel ring or flange is used as a sealing surface, and the flange is used to press them tightly.

Stainless steel spectacle blind has better anti-corrosive function than other material of spectacle blinds.ASME B 16.48 is a commonly used standard for spectacle blindThe joint face can be RF (Raised Face), FF (Flat Face), RTJ (Ring Joint),it is depend on the type of flanges.

Slip on flange also named as SO flange. SO flanges slip over pipes and are designed to bit slightly bigger on the inside than the pipe. They connect to the pipe through a fillet weld at the flange top and bottom.

Stainless steel pipe fittings including Tee,Cross, Elbow, Reducer, Coupling, Nipple, Plug & Cap,Union.They can be connected with pipes by welding, socket and thread.

Class 1500 SO flange Flanges have many pressures:CL300, CL600, CL900, CL1500, CL2500.Flanges have five face types:RF RTJ FF MF TG. Slip on flanges can slip on the pipes and welding with the pipes.

Flange provides a long tapered hub for welding to pipes , it is used in high pressure systems and suitable for both cold and hot temperatures.
